Magnetic motor generator having a floating flywheel

ABSTRACT

A magnetic motor generator that produces electric power by rotating a one piece magnetic floating flywheel assembly that is operated by a linear induction motor and repelled upward by a stationary natural magnet. The floating flywheel assembly magnetic axel rotates inside magnetic collar bearings, which have repelling stationary magnets to center the axel at speed. The floating flywheel assembly rotors move inside generator stators to generate electric power. The floating flywheel assembly has no physical contact with other components to prevent bearing losses at speed. A timing computer controls the operation of the linear induction motor, assesses the speed of the floating flywheel assembly and fires only when necessary to maintain rotation. The moving components are enclosed in a vacuum chamber to prevent wind resistance, or windage losses at speed. Surplus electric power can ether be stored/used by the system or used to supply a load.

FIELD OF THE INVENTION

The present invention relates generally to electric power generation, and specifically to generators that make use of natural forces.

BACKGROUND OF THE INVENTION

Many conventional designs already exist for producing electricity by spinning the rotor assemblies of AC/DC generators make use of natural forces, such as generators that use flowing water, as in hydroelectric systems, or by the use of wind-power, such as in wind turbine systems. There are also thermal systems drawing heat from the ground, which turns steam-powered turbines, which in turn rotate a generator to produce electricity. Solar powered electricity produced by systems that use photovoltaic solar panels are also commonly known. Such conventional designs suffer several disadvantages.

One disadvantage of such conventional designs is that they often rely on weather conditions to generate power. Hydroelectric power relies on the water supply and rainfall conditions. Wind turbines rely on wind conditions and weather systems moving through a given area. Thermal power will rely on the small abundance of hot-springs or other natural heat sources to produce the steam needed to operate the systems. Solar power can only be achieved in the daytime and also relies on sunny weather. Weather conditions can be unpredictable and often unreliable.

Another major disadvantage of such conventional designs is that they are usually fixed to one given location. With the exception of small portable solar panels, such systems are often fixed to the environment where they are originally installed and sometimes take up a large amount of space.

SUMMARY OF THE INVENTION

The present invention incorporates a magnetic motor generator having a floating flywheel that can overcome some of the disadvantages of other known electric power generating systems that make use of natural forces. An advantage of the present invention is that it will not rely on weather conditions to generate electric power. Another advantage of the present invention is that it will also be capable of providing portable electric power. The present invention can easily be installed where needed to deliver electric power at the source. Optionally, the present invention can be installed in an ocean going ship-based application to deliver emergency or transient peaking power for ship-based systems. Optionally, the present invention can be installed in ground transportation systems to deliver additional standby power to ground-based hybrid power systems, or in ground facilities where space is limited.

The present invention uses a combination of natural magnetic force and powered magnetic force to rotate a floating flywheel, which in turn rotates the rotors of an AC/DC generator application in order to generate electrical power. The present invention is the first of its kind to use the specific combination of components that comprises this new system. The floating flywheel assembly in the present invention will maximize the operating efficiency, mechanical advantage and viability of the system. Optionally, the present invention can be configured with a spin-type flywheel that rotates horizontally to the ground, as well as a roll-type flywheel that rotates vertically to the ground.

The floating flywheel assembly of the present invention is comprised of several parts held together as one moving piece. The floating flywheel assembly is comprised of a heavy magnetic wheel and a metal disk that are rotated by a linear induction motor. the flywheel axel is held in place by magnetic collar bearings, such as active magnetic bearings, to reduce bearing losses at speed. The axel is connected to the flywheel and a rotor section of an electric generator, wherein the whole floating flywheel assembly itself is held away from the ground and all other components by an additional larger stationary natural magnet. The floating flywheel portion of the present invention will create a gap of space between itself and all other components to eliminate friction between itself and all other components.

Additionally, the present invention uses a linear induction motor to rotate the floating flywheel assembly by powered magnetic force, wherein the linear induction motor will have a gap of space between itself and the floating flywheel. A timing computer controls the operation of the linear induction motor. The purpose of the timing computer is to assess the speed of the flywheel and then fire the linear induction motor only when necessary to maintain the flywheel rotation. The purpose of the controlled firing of the linear induction motor is to conserve energy and minimize losses, keeping the linear induction motor offline as much as possible. The flywheel will free-spin at speed, without being constantly driven by the linear induction motor. As the flywheel slows down, the linear induction motor will fire, controlled by the timing computer, only when necessary and with minimal power to keep the flywheel rotating at speed.

Additionally, the present invention uses a vacuum chamber around the rotating floating flywheel assembly and generator component and all moving components of the present invention to prevent wind resistance, or windage losses at speed, such as excessive air passing over the flywheel.

The present invention provides for the expanded operating efficiency of current electric power generation systems. If used as a flywheel battery, sometimes called a “motor generator set,” the rotating axel can have both a DC motor and/or an AC generator installed, and either can be the motor depending on whether the system is charging the battery storage from the AC/DC conduit or supplying an emergency AC power load from the batteries. The primary purpose of the present invention can be thought of as an inertia-based standby system with virtually no losses at speed, waiting to deliver a power load for emergency or transient peaking power. With no windage and no bearing losses at speed, the present invention can be thought of in standby mode, ready to deliver transient power by converting the stored rotational mechanical energy of the floating flywheel assembly back into electric power, and with minimal power to keep the flywheel rotating at speed.
